Comment 36 for bug 75324

hackel: yup i'm getting the same thing. It is insanely agitating and almost made me switch completely to KDE.

I'll see what I can do to debug this but it happens to me almost all the time. I think one time totem showed a "loading" box and then the following file-open box became the same size as the small loading splash screen. And then I've had the problem with various programs ever since.
